Answer: The steepness of a ramp affects it by making it easier or harder.
Explanation: It's a bit situational. If you were going up a steep ramp with a heavy load, it will increase the work necessary, whereas if you were going down a ramp, it would decrease the work necessary. If you need this simply put, think about biking up and down a hill. It would be easier going down than up.
Covalent bonds can be classified as nonpolar and polar covalent given the electronegativity difference between two atoms (ΔEN).
Nonpolar covalent bond electrons are shared equally between two atoms, polar covalent bond electrons are shared unequally, atoms have partial charges, ionic bond electrons are completely transferred to one atom, full charges present. Therefore, the greater the electronegativity difference, the greater the bond polarity. Let's determine the types of bonds present in the compounds and arrange the ones with polar covalent in order of increasing ΔEN. Sulfur and oxygen are both nonmetals so the substance is covalent. Sulfur has EN = 2.5 and oxygen has EN = 3.5. Since there is an electronegativity difference, the S−O bonds in the substance can be classified as polar covalent bonds.

Define the problem
Explanation:
The first step in a scientific investigation is to define the problem at hand. Definition of a scientific problem makes a scientific investigations possible.
- When preliminary observations are made about a phenomenon. A lot of questions as to why such things occur will arise.
- From the question, we can state the problem and the likely causes.
- The first portal in an inquiry is problem definition.
- This would them lead to the formulation of a hypothesis which contains problem statement and likely causes.
- The hypothesis leads to the design of an experiment from which investigations using experiments can be done.
- The data from the experiments are collected and analyzed.
